Yes.
Fiber optic cable is not subject to EMI and RFI interference because it transmits data using light signals through glass or plastic fiber strands, rather than electrical signals through copper conductors. This makes fiber optic cable ideal for environments where high levels of interference are present, such as near power lines or in industrial settings.
A T3 line runs at speeds of 44.736 Mbps. Faster alternatives include ethernet connections like 10 Gbps fiber optic or higher-speed leased lines such as OC-3, OC-12, or OC-48 lines, which offer significantly faster data transfer rates.
Yo­u hear ab­out fiber-optic cables whenever people ta­lk about the telephone system, the cable TV system or the Internet. Fiber-optic lines are strands of optically pure glass as thin as a human hair that carry digital information over long distances. They are also used in medical imaging and mechanical engineering inspection.
Some items that resemble the path of light when it travels through space include laser beams, fiber optic cables, and mirrors reflecting light. These items demonstrate how light can travel in straight lines and be redirected or channeled in specific directions.
Magnetic lines of force are called magnetic field lines.

These days it's all fiber optic lines. I don't think you will be able to find anyone to do this.
Optic ADSL, or Asymmetric Digital Subscriber Line, typically does not function with optical fiber as it is designed to work over traditional copper telephone lines. ADSL uses electrical signals transmitted over these copper lines to provide internet access. In contrast, fiber optic technology uses light signals transmitted through optical fibers, offering faster speeds and higher bandwidth. For fiber optic connections, technologies like FTTH (Fiber to the Home) or FTTC (Fiber to the Cabinet) are used instead of ADSL.
It can be either or depending on the circuit, here's a link that will help you more: http://communication.howstuffworks.com/fiber-optic-communications/fiber-optic.htm

T-Lines are mostly high-speed fiber optic communications lines. (example - T1, T2, T3 etc...)

There is only 1 answer,corporate greed.
There are many purposes of a fiber multiplexer. Fiber multiplexers are made to allow the transport of multiple E1 or T1 lines and Ethernet over fiber optic links. Fiber multiplexer also allow voice (phone) over fiber fiber transmission.
Its the cable used now days for technology lines. In the old days they would lay copper lines, and now optic cable are lighter, faster and cheaper. This has been a brake through.
